摘要: 采用向量空间距离模式识别法鉴别海面溢油源,研究出4个激发波长和4个发射波长用作数据处理的信息点.对未风化的和风化过的原油,燃料油和润滑油数据进行了研究.并采集了十多条船上的油品验证了方法的可靠性.给出了实验条件下的最小向量空间距离,建立了荧光光谱鉴别海面溢油源的新技术.Abstract: Anew pattern recognition technique of fluorescence spectra based on vector distance in n-dimensional space was established for the source identification of oil spills on sea.Four wavelengths of both excitation and emission were used as digitizing points of fluorescence spectrum.Three unweathered crude oils,four heavy fuels and two lubricating oils were analyized,and their digitized fluorescence spectra were studied.The reliability of this pattern recognition technique was tested by analyzing 11 bunker oils collected from different ships,and the smallest vector distance under the experimental conditions was Aiven.
